The core gyroid is defined implicitly as:

sin(x)⋅cos(y)+sin(y)⋅cos(z)+sin(z)⋅cos(x)=c

The gyroid_printable_cube is based on a famous implicit surface equation known as the gyroid, discovered by Alan Schoen in 1970. It’s a type of triply periodic minimal surface (TPMS), meaning it repeats in 3D and has no sharp edges or intersections.

🧠 Properties of the Gyroid:

• No straight lines
• No planar symmetry
• Extremely strong but lightweight
• Found in nature (butterfly wings, lipid bilayers)
• Used in lattice structures, heat exchangers, and 3D-printed metamaterials
